[0072] The above scheme is adopted: when the clamping block 524 needs to move outward, the transmission rod 601 slides on the outer surface of the support column 603 with the transmission rail 602 as the path, so that the transmission rod 601 moves to the left, the transmission rod 601 drives the first support block 522 to move to the left, and the first support block 522 drives the clamping block 524 to move outward; the support column 603 mainly serves to provide a support point for the transmission rod 601 and assist in sliding.

[0073] refer to Figure 3 As shown, the pressing assembly 7 includes:

[0074] Fixed block 701: The rear end surface of the fixed block 701 is fixedly connected to the inner surface of the protective shell 521;

[0075] Connecting rod 702: the connecting rod 702 penetrates the inner surface of the fixing block 701, the lower surface of the connecting rod 702 contacts the upper surface of the transmission rod 601, and the upper end surface of the connecting rod 702 is arranged on the locking assembly 8;

[0076] Second pressure relief spring 703 : The second pressure relief spring 703 is sleeved on the outer surface of the connecting rod 702 , and the lower end surface of the second pressure relief spring 703 is fixedly connected to the upper surface of the fixing block 701 .

[0077] Adopting the above scheme: when the transmission rod 601 needs to move to the left, the connecting rod 702 moves downward, and the lower end surface of the connecting rod 702 squeezes the upper surface of the transmission rod 601, so that the transmission rod 601 moves to the left; the fixed block 701 mainly serves to provide a fulcrum for the connecting rod 702 and a path for the movement of the connecting rod 702.

[0078] refer to Figure 3 As shown, the positioning assembly 8 includes:

[0079] Second support block 801: the lower surface of the second support block 801 is fixedly connected to the connecting rod 702 and the upper surface of the second pressure relief spring 703;

[0080] Second sliding groove 802: The second sliding groove 802 is provided on the upper surface of the second supporting block 801;

[0081] The locking slot 803 is provided inside the protective shell 521;

[0082] Locating member 804: Two locking members 804 are provided, and the lower surfaces of the two locking members 804 are both slidably connected to the inner surface of the second sliding groove 802, and the opposite side of the locking member 804 is in contact with the locking groove 803, and the second telescopic component 9 is arranged between the locking members 804.

[0083] The above scheme is adopted: when the connecting rod 702 needs to move downward, the staff pinches the locking piece 804 to make the locking piece 804 move to the opposite side along the inner surface of the second sliding groove 802 until the area between the locking pieces 804 is smaller than the area of ​​the locking groove 803, and then moves the locking piece 804 downward until the opposite side of the locking piece 804 is in close contact with the inner surface of the locking groove 803. While the locking piece 804 moves downward, it drives the second support block 801 to move downward together. The second support block 801 moves downward to squeeze the connecting rod 702 and the second compression spring 703, so that the connecting rod 702 moves downward and the second compression spring 703 is deformed.

[0084] refer to Figure 3 As shown, the second telescopic assembly 9 includes:

[0085] Second telescopic column 901: both left and right ends of the second telescopic column 901 are fixedly connected to the opposite side of the locking member 804;

[0087] The above scheme is adopted: when the locking member 804 moves to the opposite side, the locking member 804 squeezes the second telescopic column 901 and the third decompression spring 902, so that the second telescopic column 901 shortens inward and the third decompression spring 902 shortens inward; when the locking member 804 enters the locking groove 803, the third decompression spring 902 releases its elastic force, pushing the locking member 804 to move outward along the inner surface of the second sliding groove 802 until the outer surface of the locking member 804 is in close contact with the inner surface of the locking groove 803.

[0088] The working principle of this utility model:

[0089] During use, when the nozzle 3 needs to be protected and maintained, the staff will sleeve the protection ring 510 on the outer surface of the nozzle 3. Before moving the protection ring 510 along the outer surface of the nozzle 3, the staff will pinch the locking member 804 to move the locking member 804 to the opposite side along the inner surface of the second sliding groove 802. The locking member 804 squeezes the second telescopic column 901 and the third decompression spring 902 to shorten the second telescopic column 901 inwardly and the third decompression spring 902 inwardly until the area between the locking members 804 is smaller than the area of ​​the locking groove 803, and then move the locking member 804 downward. When the locking member 804 enters the locking groove 803, the third decompression spring 902 releases its elastic force, pushing the locking member 804 to move outward along the inner surface of the second sliding groove 802 until the outer surface of the locking member 804 is in close contact with the inner surface of the locking groove 803. When the locking member 804 moves downward, it drives the second support block 801 to move downward together. The second support block 801 moves downward to squeeze the connecting rod 702 and the second decompression spring 703, so that the connecting rod 702 moves downward and the second decompression spring 703 is deformed. When the connecting rod 702 moves downward, the lower end surface of the connecting rod 702 squeezes the transmission The upper surface of the movable rod 601 causes the transmission rod 601 to slide on the outer surface of the support column 603 along the transmission rail 602, so that the transmission rod 601 moves to the left, and the transmission rod 601 drives the first support block 522 to move to the left, and the first support block 522 drives the clamping block 524 to move outward. After the movement, the protective ring 510 is moved to the left along the outer surface of the nozzle 3, and the movement of the protective ring 510 drives the protective shell 521, and the protective shell 521 can drive the clamping block 524 to move to the left. The clamping block 524 is squeezed by the clamping groove 523, so that the clamping block 524 moves to the opposite side along the inner surface of the first sliding groove 525. The clamping block 524 moves and squeezes the first telescopic column 531 and the first pressure-relief spring 532, causing the first telescopic column 531 to shorten inward and the first pressure-relief spring 532 to contract inward, until the area between the clamping blocks 524 is smaller than the area of ​​the clamping groove 523, so that the clamping block 524 can enter the clamping groove 523. After the clamping block 524 enters the clamping groove 523, the first pressure-relief spring 532 releases its elastic force outward, causing the clamping block 524 to move to the opposite side along the inner surface of the first sliding groove 525 until the opposite side of the clamping block 524 is in close contact with the clamping groove 523, thereby achieving the clamping purpose.

[0090] To sum up: this construction site dust removal device, through the base 1, main body 2, nozzle 3, nozzle cover 4, protective mechanism 5, transmission assembly 6, downward pressure assembly 7, positioning assembly 8 and second telescopic assembly 9, solves the problem that the nozzle on the spray dust suppression device is not used for a long time and placed aside, causing the nozzle to be soaked with dust and particulate matter in the air, resulting in the nozzle being blocked by impurities or the spray dust suppression device being damaged when the spray dust suppression device is used next time.
